Working Principle

A film capacitor utilizes a thin plastic film to separate two metal plates that are both electrically conductive. This arrangement creates a dielectric layer that is used to store electrical energy and form the capacitor. As an electrical current flows through the device, the electrons are pushed by the electric field. The electric field creates an electrical charge of positive and negative charges on either side of the dielectric layer, storing energy. This energy can then be discharged when required with minimal losses.
